The object of the invention is to provide.

a tank of thinsheet metal and so constructed as to entirely eliminate,or at least greatlyreduce. the sweating of the tank.

Flushing and similar tanks collltl'tlclfll tl" sheet metal and enann-ledare sightly and sanitary but are objectionable on account of thesweating or condensation of n oistnre on their outer surfaces. Variousconstructions and arrangements to avoid sweating or take care of thecondensation have been devised.

The present invention has for its object a tank 0 the character namedwhich is so constructed as to eliminate, or practically eliminate, thesweating. or condensation referred to,

T e invention comgzises a tank constructed as hereinafter descri d andclaimed.

In the aceom anying drawing Figure 1 is a rear view of t e tank partlybroken away; Fig. 2 is a vertical transverse section through the same;Fi 3 is a plan view, partly broken away; l ng. 4 18 a perspective viewof the blank from which the bot y )ortion is formed showing the samepartly -nt. up; Fig. 5 is a sectional view of a modification: and Fig.(l is a, perspective view of icntmn.

.'l be tank may he of any suitable shape and size, preferably ofrectangular form with roamed corners as is the vpreaent practice inllnshin tanks. The tank has a front wall 1, em walls 2, rear wall 3 andbottom 4.

The front and end walls are double, that is formed with an outer Sheet 5and an inner sheet 6 se arated by the intervening air :4 race 7. '1 hisdouble wall at the front and t to two ends is preferabl formed from a.single sheet which is out o the she )e shown in Fig. 4 and then foldedalon f t a line 8 to bring the two parts paralle and form the roundedconnecting portion 9 which forms the top edge of t 10 ank.

These parts are united in any sintable'sgay, such as bysolderm brazm or-whldtng, Kreferably by welding by t to eleetti low pipesystem. Smee the edgds d! the parts abut. a single welded joint servedto unite the bottom or back to the indohnd front wall portions and alsounite the of the inner and outer end wall= There is a vertical joint 14of this character along the back near each end and also a joint 15 onthe bottom extending acroI-near each end and near the front. t vi.

Fig. doubled walls have their open al a upwardly. the rounded conncctmgportaen 9 being at the bottom. In this case-theta space 7 is nothermetically sealed, audit-litre. l to 3.

The entire body after completion iscovered w|th enamel and the surfaces of the air space 7 will be eithergalvanised, paintedmr enameled in order to prevent. corrosion. For thisa one of the sheets will be provid ytth a hole through which the coatingl quid can be mly. Theba' wall portions;

A cover of any su table shape will be provided. The tank will beprovided with the usual openings in its bottom or elsewhere for thesupply pipe or valve and for the flushing valve or outlet pipe. and willalso be provided with any smtable valve mechanism and operating means.

The tank described has a body formed of two sheets unitedhy a ,sm le omtthereby reducing to a nnnnuum tie abor costin manufacture. The front andand walls are hollow and in the preferred form provide a hermeticallysealed dead air space which practically overcomes all sweating orcondensatimu- The back is usually in contact with the wall so thatsweating at this point is reduced to a minimum aml the bottom is ofrestricted area so that the amount of condensation thereon is notsutlieieut to he objectionable. It may be covered by a water-proof feltmat which acts as a noncondnctor and prevents sweating.

What I claim is:-

l. A sheet metal flushing or ltkG tank having its front and end wallsformed double and spaced apart and providing a hermetically sealed airspace, and a bottom and back secured to said double walls.

2. A sheet metal flushing or like tank havmg double walla spaced apartand formed from a single sheet of metal doubled on itself to form theinner and outer walls, and a bottom secured to said double walls.

8. A sheet metal flushing or like tank having double walls spaced apart.said walls being cmnposed of a single sheet of metal doubled on itselfto form the inner and outer walls, the bent or curved portion formingthe top of the tank, and a bottom securfid to the free lower edges ofsaid double wa 4. sheet metal flushing tank havin front and end wallsspaced a art and fOllllQt from a single sheet of meta doubled on itselfto form the Inner aml outer walls, the bent or curved part forming thetop ofth tank, and a bottom and back secured to t e lower so edges ofsaid walls.

' 5. A sheet metal flushing or like tank having double Walls spacedapart and formed from a single sheet of metal doubled on itself tofurmthe inner and outer walls, a rear wall mured to the free verticaledgesof the double end walls and a bottom secured to the lower edges ofthe double end and front walls.

0. A sheet metal flushing or like tank having double walls spacedapart'and formed from a single sheet of metal doubled on itself to formthe inner and outer walls, the edges of the outer portion bein bentinwardly and meeting the edges 0 the inner portion, and, a bottomsecured to the free edges of said outer and inner walls.

7. A sheet metal flushing and like tank having double front and rearwalls spaced apart and formed from a single sheet of metal doubled onitself to form tlie inner and outer walls. the outer wall portihar hav;ing its rear vertical edges and its edges bent inwardly and me ting theedgesv of the inner wall, and the back and bottom having their edgescontactin with the free edges of the wall portion an 'oined thereto.

8. A sheet metal flushing or ike tank havbott m 7 ing double walls witha hermetically sealed air space there-between. and a back and bottom,the meeting edges of said parts being united by a welded joint.

i). A sheet-metal flushin or like tank having double walls separat 'by ahermetically sealed'air space, and a bottom and back, the

edges of the bottom and back end of the inner and outer wall portionsbeing united by a single joint. k

10. A sheet metal flushing or like tank having the meeting edges of thesheets welded and reduced to substantially the thickness of the sheets.the whole being covered with a coating of enamel.

11. A sheet metal tiushing or having the meeting edges of the sheetsjoined by a butt weld joint which is and the whole covered with acoating of enamel.

In testimony whereof, I have hereunto set my hand.
